Assistive technology means any item, piece of equipment or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve the functional capabilities of children with disabilities
(Federal Register, August 19, 1991, p. 41272).
The federal regulations went on to state that an array of services also is included when considering applications of assistive technology. Such services include activities such as evaluation of a person's needs for assistive technology devices, purchasing or leasing assistive technology devices for people, designing and fabricating devices, coordinating services offered by those who provide assistive technology services, providing training or technical assistance to a person who uses assistive technology, and training and technical assistance to those who work with people who use assistive technology devices, such as teachers or employers.
Assistive technologies include mechanical, electronic, and microprocessor-based equipment, non-mechanical and non-electronic aids, specialized instructional materials, services, and strategies that people with disabilities can use either to (a) assist them in learning, (b) make the environment more accessible, (c) enable them to compete in the workplace, (d) enhance their independence, or (e) otherwise improve their quality of life. These may include commercially available or "home made" devices that are specially designed to meet the idiosyncratic needs of a particular individual. (Blackhurst & Lahm, 2000)
